However, because the frictional force of metallic support and ball 12' is larger, causing existing bearing assembly 1' in metal branch
Rotates effe in frame is poor.
Utility model content
Based on this, it is necessary to which there is provided one kind for the bad technical problem of rotates effe for the bearing assembly of prior art
Bearing seal assembly.
The utility model provides a kind of bearing seal assembly, including：Metallic support, plastic casing, ball and needle roller
Bearing, shell described in the support support, the shell is provided with outer casing through hole, and the ball is placed in the outer casing through hole
Interior, the ball is provided with the ball through hole coaxial with the outer casing through hole, and the needle bearing is placed in the rubber
In ball through hole.
Further, in addition to an at least lid, the lid is provided with the lid through hole coaxial with the outer casing through hole,
The end of the lid through hole is connected with the end of the outer casing through hole by contiguous block, and end and the institute of the lid through hole
Reserved between the end for stating outer casing through hole and sealing ring is set in accommodating cavity, the accommodating cavity.
Further, the cross section of the sealing ring is letter k shapes.
Further, the end of the outer casing through hole is provided with shell neck, and the end of the lid through hole is provided with lid
Neck, shell neck and the lid neck described in the contiguous block difference clamping.
Further, the contiguous block is snubber block.
Further, the shell includes the case member of two mutual buckles.
Further, the inner surface of outer cover is provided with the convex tendon that at least one is interference fitted with the ball.
The utility model between ball and metallic support by setting plastic casing, due to plastic casing and metal branch
Coefficient of friction between frame will be much smaller than the coefficient of friction between rubber and metallic support, therefore, ball of the present utility model
And internal needle bearing can rotate in metallic support well so that the running of bearing seal assembly is more smoothly.

Embodiment
Further illustrate embodiment of the present utility model below in conjunction with the accompanying drawings.Wherein identical parts phase
Same reference is represented.It should be noted that below description in use word "front", "rear", "left", "right", " on " and
" under " direction in accompanying drawing is referred to, word " interior " and " outer " are referred respectively to towards or away from the side of particular elements geometric center
To.
As shown in Fig. 3~Fig. 5, a kind of bearing seal assembly 1 of the utility model, including：Metallic support 11, plastic casing
12nd, ball 13 and needle bearing 14, shell 12 described in the support of support 11, the shell 12 are provided with outer casing through hole,
The ball 13 is placed in the outer casing through hole, and the ball 13 is provided with the ball coaxial with the outer casing through hole
Through hole, the needle bearing 14 is placed in the ball through hole.
Plastic casing 12 is preferably that duroplasts is made.During assembling, the axis body 2 of jackshaft is passed through into needle bearing 14, passed through
Needle bearing 14 carries out support to axis body.Simultaneously as the coefficient of friction between plastic casing 12 and metallic support 11 is remote small
Coefficient of friction between rubber and metallic support, therefore, the energy of needle bearing 14 of ball 13 of the present utility model and inside
Rotated well in metallic support 11 so that the running of bearing seal assembly is more smoothly.
In one of the embodiments, in addition to an at least lid 15, the lid 15 is provided with and the outer casing through hole
Coaxial lid through hole, the end of the lid through hole is connected with the end of the outer casing through hole by contiguous block 16, and described
Reserved between the end of lid through hole and the end of the outer casing through hole and sealing ring is set in accommodating cavity 17, the accommodating cavity 17
18。
Preferably, lid 15, contiguous block 16, accommodating cavity 17 and sealing ring are set respectively in two ends of outer casing through hole
18。
The present embodiment sets sealing ring 18, by setting sealing ring 18, so that avoid vehicle pollutant from entering needle bearing,
Realize good sealing protection.Simultaneously as bearing seal assembly has had good sealing in itself, therefore without being collected
Into in seal closure, placed so as to the different designs demand according to jackshaft.
In one of the embodiments, the cross section of the sealing ring 18 is letter k shapes.
The sealing ring 18 of the present embodiment is k shape rings, is brought into close contact so as to the axis body 3 effectively with jackshaft, is improved
Sealing.
In one of the embodiments, the end of the outer casing through hole is provided with shell neck, the end of the lid through hole
Provided with lid neck, shell neck and the lid neck described in the difference of contiguous block 16 clamping.
The present embodiment by setting shell neck, lid neck so that contiguous block can well with shell, lid
Clamping is carried out respectively.
